Driveline Dynamics Modelling and Analysis of Automotive Launch Process

On the basis of the combination of lumped parameter method of systematic dynamics and finite element method of structural dynamics, a simulation model that synthesizes each part and non-linear factors such as clutch friction characteristics, multi-stage stiffness of torsional damper, gear backlashes and tire longitudinal characteristics of the driveline system was established. With the systematic-structural dynamics hybrid model, the shudder phenomenon during clutch engaging process and low-frequency shuffle after engagement along with clonk phenomenon were reproduced when the vehicle was in launch condition. Then, the influencing factors of clutch engagement process, gear backlash and the pre-damper stiffness were analyzed.
